Specification of Letters Patent.

Patented July 17, 1906.

Application filed August 19. 1905. Serial No. 274,846.

To all whom it may concern.-

Be it known that I, WILLIAM W. HARRIS, a citizen of the United States, residing in the borough of Manhattan, city, county, and State of New York, have invented certain new and useful Improvements in Carbid- Lamp Filling-Funnels, of which the following is a specification, reference being had therein to the accompanying drawings, in which Figure 1 is a vertical sectional view showing the filling-funnel in positionin the fillingneck of a carbid-feed acetylene-lamp; Fig. 2,

.a vertical sectional view of the funnel removed from the lamp, showing the closure device sealing the end of the funnel and preventing the passage of carbid therethrough.

One of the many objects of this invention is to provide a simple device adapted to be placed in the filling-neck of a carbid-feed acetylene-gas lamp and through which the carbid charge may be poured, suitable devices being provided by which the passage of carbid through the funnel may be interrupted when the carbid-holder is filled to the desired point, the excess carbid remaining in the funnel and being withdrawn with said funnel from the lamp.

A further object of the invention is to provide a filling-funnel which will act as a gage, so that the carbid-holder of the lamp will be filled only to a certain point.

Referring to the various parts, A designates the carbid-holder, and B the fillingneck of an acetylene-gas lamp of that type wherein carbid is introduced into the carbidholder through the lower end thereof, as shown and described in the patent to Charles W. Beck, No. 790,868, dated May 23, 1905.' As shown in the drawings, the carbid-hop er is inverted and the valve-seat removed efore the introduction of the filling-funnel.

The filling-funnel proper consists of the tapered body part 1, whose contour corresponds substantially to the contour of the interior of the fillingneck and is slightly smaller in diameter than the filling-neck. Across the enlar ed end of the funnel is a bridgepiece 4, w 'ch is formed at the axial center of 5c the funnel with an aperture in which slides a longitudinal rod 5. To the inner end of this rod is secured a long tube or cap 6, which is adapted to fit over and to receive the feed plunger or valve 7 of the lamp. To the inner end of this cap is secured an outwardflaring deflector and closure device 8, which is larger in diameter than the diameter of the feed-valve housing 9 in the carbid-hopper of the lamp and serves when in position to deflect the carbid away from said housing. To the outer end of the rod 5 is secured a fingerhold 10, said hold being shown in the drawings as a ring.

When the device is in position as shown in Fi 1, carbid may be oured through the funnel into the carbidolder until the carbid reaches the filling-level at the lower end of the funnel, which will indicate that the required amount of carbid has been supplied. In removing the device from the lamp the ring 10 is grasped and the cap 6 drawn from the plunger. The deflector and closure device will move upward until it contacts with the lower smaller end of the funnel, after which the two parts will move together. Any excess of carbid poured into the funnel will remain therein and will be removed with the funnel, the closure device serving to retain it therein While it is being removed from the lamp. This excess carbid can be delivered into the carbid can or receptacle by merely forcing down the closure device, as will be readily understood.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A filling-funnel for carbid-feed acetylene-gas lamps comprising a body part, a cap therein adapted to receive the feed-valve of a lamp, a deflector and closure device carried by said cap, and means to move said cap to close the lower end of the funnel when the funnel is being withdrawn from the lamp.

2. A filling-funnel comprising a body part, a central tubular cap therein and adapted to receive the feed-plunger of a lamp, a deflector secured to the end of said cap and adapted to seal the inner end of the funnel.

3. A filling-funnel comprising a funnel proper, a longitudinally-movable tubular cap mounted therein at the inner end thereof, In testimony whereof I hereunto affix my said cap being adapted to receive the feedsignature, in the presence of two Witnesses,
